This invention relates to a method, a computer program, a computer program product, a system, a sender, a receiver and a session description protocol for transmitting common data from one sender () to a plurality of receivers () within a transmission session, comprising communicating () at least one session parameter, which is related to said transmission of said common data within said transmission session, to said plurality of receivers () via a communication protocol; and transmitting said common data from said sender () to said plurality of receivers () within said transmission session. The invention particularly relates to broadcast/multicast transmission of common data in a wire-bound and/or wireless network, wherein a File Delivery over Unidirectional Transport FLUTE protocol is used.

Conveying parameters for broadcast/multicast sessions via a communication protocol

An object delivery session, such as a File Delivery over Unidirectional Transport (FLUTE) session, is joined and a description of a plurality of objects provided by the session are provided. The description indicates one or more groupings of the plurality of objects. An interesting object is determined from the plurality of objects. Based on the interesting object and the description of the plurality of objects, one or more of the plurality of objects are identified for downloading.

Grouping of session objects

The invention relates to a method for file delivery in a system capable of one-to-many transmission, the method comprising transferring one or more data blocks from a sender to at least one receiver, identifying a data block expected to be received but not received at all or incorrectly received at the receiver, and taking action to re-transmit said data block. In the method, said identification is performed on the basis of a block number, an encoding identifier and certain other identification information.
